井震匹配构造建模技术在密井网区的应用——以大庆长垣萨北油田BRSX区块为例

The Application of Well-seismic Matching Technique in Dense Well Pattern Areas

针对油田密井网区的井资料特点以及深度开发措施调整对构造模型的要求,仔细分析了井、震资料在建立构造模型方面的优势和局限性,在此基础上采用井震匹配方式进行构造建模。通过井点定位、构造趋势参考、解释成果约束、动态资料验证等手段建立了大庆长垣萨北油田BRSX区块的精细构造模型。该方法融合了构造解释和建模思想,建立的模型精度高,和生产动态结果相符,在利用模型进行注采系统调整过程中见到良好效果。

In order to meet the data requirement in dense well pattern areas and structural modeling for in-depth production adjustment,the advantages and limitations of structural modeling using well-seismic data were analyzed attentively.On the basis of analyzing the advantages and limitations of well and seismic data for structural models,a series of techniques to match well data and seismic data are applied to establish a fine structural model for B23 XBlock through well point positioning,reference of structural trend,constraints of interpretation results,and validation of dynamic data.This method combines with the ideas of structural interpretation and modeling,the established model has high accuracy and it is consistent with production performance.It is used for the adjustment of injection-production system and good results are obtained.
